    Abstract
    Time-frequency representation plays a significant role in the analysis of non-stationary signals. A number of such representations have been reported in the literature with each having its own strengths. In this paper, an alternative time-frequency analysis method, Dual Window Fourier Transform has been suggested which enables compact localization of the signal components in joint time-frequency plane. The method utilizes two windows of optimal length for improving the resolution of the analyzed signal. The main contribution of this work is in the algorithm developed to find the...
